Gaby,
I don't know if your brother's business is in retail, but you might
try asking the Florida Retail Federation about merchant service
providers. You can contact them at
www.frf.org or
1-888-357-3824.
Another source of information might be a counselor at the Florida
Small Business Development Center closest to you. They are not-for-
profit centers funded by the U.S. SBA and Florida universities. Here's
a contact list.

Hope that helps.
